got me a 2500hd with an nv4500 5 speed, granted its not race truck, its a powerhouse that goes 25 mph in second gear. so.........im looking for a low end cam for an ls motor. the majority make power as the rpm;s go up, is there a company around that makes an off idle cam for a lsx? also does anybody on this site have experience with this type of cam in lsx.
